Investigation of Channel Usage and Packetloss in a MANET Testbed for Stairs Indoor Scenarios.
ABSTRACT In recent years, Mobile Ad hoc Networks (MANETs) are continuing to attract the attention for their potential use in several fields. Mobility and the absence of any fixed infrastructure make MANETs very attractive for mobility and rescue operations and time-critical applications. In this paper, we analyse our MANET test bed regarding packet loss metric considering the Optimized Link State Routing (OLSR) protocol. We implemented two models. One when all the nodes are static and another one when one node is moving. In this work, we assess the performance of our MANET test bed in terms of packet loss, considering IEEE 802.11 channel usage in the environment. From our experiments, we found that the OLSR protocol has a good performance when nodes are in stationary state. We observed that the number of packet loss increases after 2-hops for static model and after 1-hop for moving model. The channel usage in each floor also influences the results of packet loss.

ABSTRACT: In recent years, MANETs are continuing to attract the attention for their potential use in several fields such as military activities, rescue operations and time-critical applications. In this paper, we present the implementation and analysis of our implemented MANET testbed considering AODV and BATMAN protocols for wireless multi-hop networking. We investigate the effect of mobility and topology changing in MANET. We evaluate the performance of the routing protocols through experiments in real environment. In this work, we consider four scenarios: Static, Source Moving, Destination Moving and Source-Destination Moving. We assess the performance of our testbed in terms of throughput, number of dropped packets and delay. We found that, when routes are changing often, the BATMAN has better performance than AODV because it put the packets in a buffer. While, because AODV is a reactive protocol, it introduces some delay in the network.Proceedings of the Fifth International Conference on Broadband and Wireless Computing, Communication and Applications, BWCCA 2010, November 4-6, 2010, Fukuoka Institute of Technology, Fukuoka, Japan (In conjunction with the 3PGCIC-2010 International Conference); 01/2010

ABSTRACT: In this paper, we present a general methodology to assess the performance of an ad-hoc network equipped with a proactive routing protocol, namely the Open Link State Routing protocol. We are interested in identifying the parameters which strongly affect the overall performance. To this aim, and contrary to the common use of computing means and variances only, we use a hypothesis test-based toolkit, because of the large number of factors which interact with our testbed. We discovered that there is a hop-count threshold, after which the performance deteriorates. For instance, the statistical analysis has shown that after the hopcount threshold the variability of our data increases, i.e. a marked oscillatory behaviour arises. The results of this work confirm the need of adaptive selection of the routing protocol parameters.Advanced Information Networking and Applications, 2007.
